Test Procedures
TEST PROCEDURE 7 – Battery Pack Voltage (Under Load)
See General Warnings on page 1-1.
1. Be sure the batteries are fully charged and that the electrolyte level is correct in all cells.
2. Connect the tester leads to the positive (+) post of battery no.1 and negative (–) post of battery no. 4 (Figure
14-10, Page 14-20) or battery no. 6 (Figure 14-11, Page 14-20).

Configuration
3. Turn the discharge machine on and record the voltage reading of battery pack while under load.
4. A fully charged set of batteries in good condition should read between 46-49 volts while under load.
5. A reading of 32-46 volts indicates discharged or failed batteries. Each battery should be checked with a
multimeter while under load.
6. A reading of 32 volts or less will not activate discharge machine. If the voltage of the batteries is below 32 volts,
the batteries are deeply discharged or have failed.
7. Recording the battery pack voltage reading while under load provides a more accurate diagnosis of the condition
of the batteries. When the discharge machine is ON, it places the battery pack under load and many times
can help determine if one or more batteries in the set have failed. Testing battery voltage while the batteries
are not under load will not always indicate the true condition of the batteries. For more information about the
batteries, refer to See Section 18 – Batteries. .
TEST PROCEDURE 8 – Key Switch and MCOR Limit Switch Circuit
See General Warnings on page 1-1.
Key Switch and MCOR Limit Switch Circuit Test with the IQDM Handset
1. Place chocks at the front wheels and lift the rear of the vehicle with a chain hoist or floor jack. Position jack
stands under the frame rails just forward of each spring mount. See WARNING "Lift only one end..." in
General Warnings on page 1-1.
2. Turn the key switch to the OFF position and place the Forward/Reverse switch in the NEUTRAL position.
3. Connect the IQDM to the vehicle.
